Spec's Stage 4 clutch is a solid hub version of their Stage 3 kit. This clutch is recommended for mainly race applications as the engagement is not completely street friendly. The core of the Stage 4 Mustang Spec clutch is the heat treated, 8-rivet hub assembly. You can be confident that this clutch will stand up to your high torque V8 powered Mustang.

Spec Stage 4 clutch is rated up to 760 ft/lb of torque. It includes a high clamp pressure plate with carbon-graphite friction material. The high torque solid hub and disc assembly make it the perfect set up for serious racers. Included is a new bearing and tool kit. If your Stang is set up for race duty with a little bit of street driving, the Spec Stage 4 clutch is just what the doctor ordered.
